The tickets brought by the Spencer's family
4 adult tickets= 
2 children tickets = 
So that would add to $35+$13 = $48
Now let's calculate the cost for Andrew family
2 adult ticket = 
3 children's ticket = 
1 senior ticket = 
So this will add to

=$43.5
(c)No. The Spencer family has spent more than the Andrew family
P.S. The part a mentioned here is not actually , yet the total cost of tickets are calculated. Hope this helps
A table top would be a good representation of a plain because it is a flat surface, and isn't a 3D object, if that makes sense. A box wouldn't be a plane because it has 6 different sides but a table only has one side and one plane. hope this helps :)
Answer:
28°
Step-by-step explanation:
soln
(x+3)°+(2x+3)°
x°+3°+2x°+3°=90°(beign complementary angles)
3x+6=90°
3x=90°_6
3x=84
x=84/3
x=28°
